About The Granite Dells 

Formed in the Pre-Cambrian era, the Granite Dells are unique granite formations created over 1.4 billion years ago. They are known for their unique rounded shape and array of orange and brown hues, creating a stunning background for both land and water recreation in the Greater Prescott, AZ area. More than just rock formations, the area of the Dells includes creeks, resevoirs, flatlands, and forest areas, supporting a wide array of biodiversity critical to the whole central Arizona region. 

A Backdrop To History 

The historical significance of the Granite Dells cannot be understated. The Dells hold signficant cultural value to the Yavapai Prescott Tribe, whose anscestors relied on Granite Creek as a key water source for crops and animals alike. By the 1860's, early Prescott Settlers began using the Dells to support  early ranching, railroad, and mining ventures. In 1903, Granite Creek was damned creating Watson and Willow Lakes, thus solidifying the locales popularity for outdoor enthusiasts. In many ways the Granite Dells were a key factor in shaping modern Prescott.

​​

Beyond the stunning views of the Dells is a rich ecosystem filled with wildlife and plants of all kinds. For example, Watson and Willow Lakes have both been deemed Important Bird Areas (IBAs) by the National Audobon Society, and the trails through the dells often serve as important corridors for an array of mule deer, javelina, coyotes and more. The rocks of the Dells themselves are also teeming with life, supporting microhabitats filled with different lizards and insects. A haven for pollenators, the Dells also boast a diverse plant population with hundreds of plant species calling the Dells home. 

An Ecological Wonder

Today, the Granite Dells is a critical part of support the public health of the Greater Prescott Community.
